It is a horizontal one-sided automatic sheet-punching machine for manufacturing exchangers for refrigerators. Its operation is: a servo motor and a suction cup select and insert fins automatically; hydraulic pipe-punching is made to make aluminum pipes and such fins fit together closely so as to maximize the efficiency of an exchanger.| Model:SKCP8-11*2/600 1 Sheet-punching capacity: 100mm~600 mm 2 Aluminum pipe diameter: ?8mm 3 Number of exchanger rows: 2 rows (sheet width 50mm, 60mm)/3 rows (sheet width 75mm) 4 Number of holes on each row: 10 5 Pitch of holes: 38.1 mm 6 Pitch of rows: 22 mm 7 Sheet-punching method: hydraulic sheet-punching 8 Sheet-punching speed: 400MM/S, return stroke 400MM/S 9 Oil pump model: VPVC-F40-A2-02 10 Oil pump motor: 5HP 4P 11 Sheet-inserting method: servo () 12 Control power supply: 24V 13 Hydraulic system pressure: 5~7mpa 14 Air source pressure: 0.5~0.7mpa (in order to ensure steady pressure, the equipment is equipped with independent supercharging system) 15 Operating speed: ˜1-2s/sheet (excluding sheet feeding) 16 Dimensions: 10,000mm (length) ×1,200mm (width) ×1,500mm (height) 17 Total weight: ˜1.5 tons(t)
